Other mother dolphins and whales have kept their calves buoyant,” mentioned Barbara King, professor emerita of anthropology on the College of William and Mary and writer of “How Animals Grieve.”
“What’s different about J35 is her persistence,” she mentioned, however then requested: “How resilient can she be? How long can she keep this up? Is she eating? Is she taking care of herself?”
The orca and her intently knit pod of whales have been noticed taking turns carrying the lifeless calf, Atkinson mentioned.

There are actually solely 75 whales, the bottom quantity in three many years, and researchers are fearful concerning the destiny of one other 4-year-old feminine orca often known as J-50 that appears skinny and emaciated.
The orcas are distinct from different killer whales as a result of they eat salmon, largely Chinook salmon, that are additionally declining, moderately than marine mammals. Individual whales are recognized by distinctive markings or variations of their fin shapes, and every whale is given a quantity and identify.
Traveling collectively in matrilineal teams, the orcas at occasions could be seen breaching round Puget Sound, even in opposition to the backdrop of the downtown Seattle skyline.
Deborah Giles, a scientist with the University of Washington’s Center for Conservation Biology, has noticed the grieving mom whale in current days. At occasions the whale dives into the water to retrieve her calf when it sinks, retrieves it and pushes the calf again to the floor.
“Sometimes she’s on her own with that calf, but a lot of time, she’s with her mom and her son and another relative. Her family has been right by her,” Giles mentioned.
